Keep your bones strong and healthy

 

Keep your bones strong and healthy - The Star

 How to Maximize Bone Health

How do I keep my bones healthy?

 BONES are a very important organ in our body and have many functions. Its role includes providing structure, protecting internal organs, anchoring muscles and storing calcium.

They also facilitate movement and are important for blood cell formation. Therefore, maintaining bone health is very important for everyone.

Normal bone metabolism is the complex sequence of bone turnover (osteoclast activity) and bone formation (osteoblast activity). The bones are continuously changing, where the old bones are broken down and replaced by new bones. This process is regulated by hormones such as parathyroid hormones, calcitonin, oestrogen, androgens, growth hormone, thyroid hormones, Vitamin D and steroids such as glucocorticosteroids.

Consultant orthopaedic surgeon at MSU Medical Centre Dr Ruzaimi Md Yusoff says, “Most people reach their peak bone mass around the age of 30. After that, bone remodelling continues, but you lose slightly more bone mass than you gain because of a decrease in osteoblast activity.

“The higher the peak of bone mass, the less likely for us to develop osteoporosis at a younger age.”

What affects bone health

The following are the risk factors which can affect bone health. Modifiable risk factors are:

Diet. A low calcium intake will cause low bone density and will lead to early bone loss causing a higher risk of fractures. Not getting enough vitamin D can also increase the risk of osteoporosis.

Physical activity. Not exercising and not being active for long periods can increase the chances of getting osteoporosis.

• Body weight. Maintaining an ideal body weight is important for bone health. This is because an extremely thin individual will have lesser bone mass.

Smoking. Research suggests that tobacco will increase the risk of osteoporosis. Women who smoke also go through menopause earlier than those who don’t smoke.

Alcohol. People who consume a lot of alcohol are more likely to get osteoporosis.

Medicines. Certain medications can affect bone health. Prolonged usage of corticosteroid medications such as cortisone, prednisolone and dexamethasone can be damaging to the bone.

Non-modifiable risk factors are:

Age. Advanced age causes thinning and weakening of the bone.

• Gender. Women have a greater risk of osteoporosis as they have less bone tissue than men. Women also lose bone faster than men because of hormonal changes that occur after menopause.

Ethnicity. Caucasian and Asian women are more prone to osteoporosis.

• Family history. A strong family history of osteoporosis predisposes an individual to develop osteoporosis at an earlier age.

Maintaining healthy bones

Maintaining bone health is important to prevent or slow down the process of bone loss.

Dietary calcium intake is extremely important. The recommended dietary allowance (RDA) of calcium for female adults aged 19 to 50 years and males aged 51 to 70 years is 1,000mg per day. The recommendation increases to 1,200mg a day for women aged 51 years and older and for men aged 71 years and older.

Good sources of calcium include dairy products, almonds, broccoli, kale, canned salmon with bones, sardines and soy products such as tofu.

Calcium supplements may also be prescribed by a doctor if needed.

Adequate vitamin D intake is important for calcium absorption. For adults aged 19 to 70 years, the RDA of vitamin D is 600 international units (IUS) a day. The recommendation increases to 800IUS a day for adults aged 71 years and older.

Good sources of vitamin D include oily fish such as salmon, trout, whitefish and tuna. Sunlight also contributes to the body’s production of vitamin D. Supplements may also be prescribed if indicated.

Physical activity especially weightbearing exercises such as walking, jogging and climbing stairs can build strong bones and slow the process of bone loss. Last but not least, avoid smoking and limit alcohol intake to help delay osteoporosis.

Signs of bone health problems

There are some signs of osteoporosis that we should look out for:

• Receding gums. A dentist might be the first person to spot signs of osteoporosis. Research suggests that if there is significant bone loss in the jaw, it could be a sign of bone loss in other areas of your body.

Chipped or brittle nails. Chipping a nail frequently could be a sign that other bones may also be brittle. Those who have low levels of collagen or calcium in their nails also do not have enough calcium in their bones.

Weakened grip. Have you started to notice that you cannot turn the doorknob easily? The strength of the handgrip and the density of the bones in the arms, hips and spine are directly related.

Fractured bones. The hips, spine and wrists are the most common body parts to fracture. Fractures occur from trivial trauma such as slight knocks, bending over or lifting items.

When to see a doctor

It’s important to seek medical attention for any type of bone pain, especially if the pain is severe, persistent, worsening over time or associated with swelling, redness, warmth, a fever, unintentional weight loss or a palpable mass or lump.

Since osteoporosis does not have any symptoms until a bone breaks, it is important to talk to your doctor about your bone health.

If your doctor feels that you are at risk for osteoporosis, a bone density test may be performedto measure the density of your bones, and assess for osteoporosis and risks of breaking a bone.

Doctors may prescribe medicine if your bones are weak and have a higher risk of osteoporotic fracture in the future. These include bisphosphonates, oestrogen agonists/antagonists, calcitonin, parathyroid hormone, oestrogen therapy and hormone therapy.

Recognition and Management of Stroke

A Department of Cardiovascular Surgery Grand Rounds from the Icahn School of Medicine at Mount Sinai presented by Stanley Tuhrim, MD, and Christopher Kellner, MD. At the end of this video, viewers will be able to: 1. To review the signs and symptoms of acute stroke. 2. To elucidate the current management of acute ischemic stroke. 3. To describe current approaches to endovascular intervention in acute ischemic stroke.
A stroke is a medical condition in which poor blood flow to the brain results in cell death.[5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding.[5] Both result in parts of the brain not functioning properly.[5] Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side.[2][3] Signs and symptoms often appear soon after the stroke has occurred.[3] If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA) or mini-stroke.[3] A hemorrhagic stroke may also be associated with a severe headache.[3] The symptoms of a stroke can be permanent.[5] Long-term complications may include pneumonia or loss of bladder control.[3]
The main risk factor for stroke is high blood pressure.[6] Other risk factors include tobacco smoking, obesity, high blood cholesterol, diabetes mellitus, a previous TIA, end-stage kidney disease, and atrial fibrillation.[2][6][7] An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes.[12][13][14] A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes.[12][15] Bleeding may occur due to a ruptured brain aneurysm.[12] Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan.[8] A CT scan can rule out bleeding, but may not necessarily rule out ischemia, which early on typically does not show up on a CT scan.[9] Other tests such as an electrocardiogram (ECG) and blood tests are done to determine risk factors and rule out other possible causes.[8] Low blood sugar may cause similar symptoms.[8]
Prevention includes decreasing risk factors, as well as possibly aspirin, statins, surgery to open up the arteries to the brain in those with problematic narrowing, and warfarin in those with atrial fibrillation.[2] A stroke or TIA often requires emergency care.[5] An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot.[2] Aspirin should be used.[2] Some hemorrhagic strokes benefit from surgery.[2] Treatment to try to recover lost function is called stroke rehabilitation and ideally takes place in a stroke unit; however, these are not available in much of the world.[2]
In 2013 approximately 6.9 million people had an ischemic stroke and 3.4 million people had a hemorrhagic stroke.[16] In 2015 there were about 42.4 million people who had previously had a stroke and were still alive.[10] Between 1990 and 2010 the number of strokes which occurred each year decreased by approximately 10% in the developed world and increased by 10% in the developing world.[17] In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths (11% of the total).[11] About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke.[11] About half of people who have had a stroke live less than one year.[2] Overall, two thirds of strokes occurred in those over 65 years old.[17]
